The race for a Michigan congressional seat once considered a Republican lock may now be up for grabs after GOP voters nominated the only candidate who managed to get on the ballot — a reindeer rancher some party officials have labeled as an extremist.

Calling it a “mess” and a “fiasco” Michigan’s attorney general has charged four people following an investigation of fake and duplicate signatures on the nominating petitions submitted by then-U.S. Rep. Thaddeus McCotter.

Tea party favorite Kerry Bentivolio has won the Republican primary in Michigan for the U.S. House seat abandoned by former Rep. Thaddeus McCotter and will face off against Democtatic nominated Syed Taj in November.
